[0004] However, this metal-immersed main carbon strip structure still has the following defects: the process is difficult and dangerous, the processing cost is high, and the uneven metal liquid immersion leads to poor product quality stability and controllability
[0005] In addition, the main carbon strips of the existing carbon skateboards have long-term contact and friction with the road network wires during work, and there are still defects such as easy cracking and large frictional resistance that lead to failures

[0031] Specific implementation: as Figure 1 to Figure 6 As shown, a main carbon strip structure of an oil-immersed pantograph carbon slide plate includes a main carbon strip 2 fixedly arranged on an aluminum holder 1, and is characterized in that an oil film layer is provided on the upper surface of the main carbon strip 2. In this way, the friction friction can be better reduced and the sliding effect can be improved.
[0032] Wherein, the oil film layer is obtained in the following manner, see Image 6 : The main carbon strip 2 is obtained by mixing carbon powder with asphalt material and pressing it. After the main carbon strip is formed, it is put into the oil 7 and boiled, and then it is kept at 65-85 ℃ for 48-72 hours.
[0033] By preparing the oil film layer in the above way, the oil molecules can be combined and attached around the carbon particles on the surface of the main carbon strip, which greatly improves the sliding friction effect of the carbon particles on t...

Abstract
The invention discloses an oil immersed type pantograph carbon sliding plate main carbon strip structure. The oil immersed type pantograph carbon sliding plate main carbon strip structure comprises amain carbon strip fixedly arranged on an aluminum holding plate and is characterized in that a layer of oil film is arranged on the upper surface of the main carbon strip. The oil immersed type pantograph carbon sliding plate main carbon strip structure has the advantages that friction resistance is low, the anti-cracking capacity is high, the electric conduction performance of the main carbon strip can be improved, the technique is simple, machining is convenient, rapid and safe, and the product quality is stable and reliable.
Description
technical field [0001] The invention relates to the technical field of a locomotive pantograph carbon skateboard; in particular, it relates to a main carbon strip structure of a pantograph carbon skateboard. Background technique [0002] Electric traction locomotives are electrical equipment that obtains electrical energy from the catenary, and are installed on the roof of the locomotive or motor vehicle. Most of the existing high-speed trains in my country obtain electric energy from the road network wires through the pantograph carbon sliding plate, and drive the traction motor to drive the train to run. The structure of the existing carbon slide plate generally includes a long and bow-shaped aluminum support and a main carbon strip fixed above the aluminum support. Remove the current. Therefore, the electrical conductivity and friction resistance of the main carbon strip are very important performance parameters. [0003] Earlier, the structure of the main carbon strip...
